Quality Control

Our Bis(2-Methyloctyl) Phthalate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, acidity, and other critical physical-chemical parameters. A Certificate of Analysis (COA) documenting these results is provided with each shipment to guarantee consistency and support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Recommended storage temperature is between 15°C and 25°C. Keep container tightly sealed when not in use to minimize moisture absorption and contamination.
